• A subheading ("NHS refuses to pay for treatment of tumour that trials showed cut deaths by 25%") above a story about parents clashing with the NHS over its refusal to fund treatments for a devastating children's cancer was open to misinterpretation. As the story and feature made clear, the decision by the NHS not to recommend that parents travel abroad for treatment is based on advice it has received as to the benefits of such treatment (Battle over child cancer drugs, 25 August, page 1).

• In a comment article about the Paralympics we incorrectly stated that Royal Mail would not be celebrating winners in the same way as Olympians. In response to public demand, Royal Mail announced a fortnight ago that it will indeed produce a stamp for each individual or team ParalympicsGB gold medal win (Why the Paralympics won't challenge perceptions, 29 August, page 35).

• In a graphic accompanying an article about GCSE examination results (24 August, page 4), two figures were accidentally transposed. The percentage of results at grades D to U was actually 30.2 in 2011 and 30.6 in 2012.

•Circumcision: the cruellest cut? was corrected because the original said John Dalton is a researcher for the UK's National Organisation of Restoring Men (Norm-UK). Dalton is a researcher for the charitable support group for circumcised men called Norm-UK, which is a separate organisation from the National Organisation of Restoring Men.

•Asil Nadir, Polly Peck and the headless chickens was corrected because the original referred throughout to "Northern Cyprus" in contravention of the Guardian's Style guide. The guide's entry on Cyprus is as follows: "Cyprus, properly known as the Republic of Cyprus, joined the EU in 2004, 30 years after Turkey invaded the northern part of the island, which should be referred to as "Turkish-occupied northern Cyprus" (the self-styled "Turkish Republic of Northern Cyprus" is recognised only by Turkey)".
